Made from naturally breathable 100% cotton, the premium quality Mainstays Feather & Down Duvet is so soft it’s like being hugged by a cloud. Its super lightweight loft is the perfect blend of goose feathers and down, providing comfort and lightness for spring and summer, or warmth and coziness for fall and winter. It also features a sewn-through design to prevent the fill from shifting—all complete with an antimicrobial finish.
